Early cordless phones operated at a narrow spectrum centered at approximately 450MHz.
Next-gen cordless phones (late 1990s) operated at narrow bandwidth centered at approx. 900MHz.
G2/G3 cellular phones operated at bandwidth centered at approx 2.4 GHz, same with wifi.
5G is a new kind of beast that spans several narrow bands with differing center frequencies: 2.4GHz, 5.8GHz, 22GHz, 47Ghz, 60GHz. Each band has subsequently been identified as causing particular types of harm.
2.4Ghz spins up water molecules (same as microwave oven, manner it cooks) which slowly cooks everyone exposed.
5.8Ghz is the doubling of this, and it has been identified as destroying the Vitamin D molecule. Curiously adjunct to the madness (since 1970s) of “sunscreen”, adjunct to Obamacare particularly identifying tanning bed businesses for additional taxation; curiously adjunct to chemtrails which have effect of reducing sunlight that would otherwise cause Vitamin D production in skin.
22Ghz happens to be the spin resonant frequency of hydrogen (H2) molecule.
47GHz resonates with mammalian cellular mitochondria, causing metabolic disruptions as shown by military studies.
60GHz interferes with oxygen (O2) molecules.
